US military high court hearing appeal of Charles Graner's conviction as Abu Ghraib ringleader

The U.S. Court of Appeals for the Armed Forces in Washington will hear arguments Monday from lawyers for Spc. Charles Graner and the government.

The Army reservist from Uniontown, Pa., is serving 10 years for stacking naked prisoners into a pyramid, knocking one of them out with a punch and ordering prisoners to perform sex acts while other soldiers took pictures in 2003.

The defense says it was wrongly denied access to then-classified documents showing that some of the detainee treatment reflected "enhanced interrogation techniques" approved by Defense Secretary Donald Rumsfeld.

The government says any relevant information was already publicly available.
